Abstract (en)

[origin: EP2933014A1] An acidic gas-containing gas treatment separation membrane is provided which is capable of separating acidic gas or methane gas from biogas containing acidic gas, such as carbon dioxide or the like, and methane gas to obtain a gas having a high methane concentration. The acidic gas-containing gas treatment separation membrane includes a polysiloxane network structure having an introduced hydrocarbon group, doped with a metal salt having affinity for acidic gas. The polysiloxane network structure having the introduced hydrocarbon group is a composite polysiloxane network structure obtained by a reaction of a tetraalkoxysilane with a trialkoxysilane containing the hydrocarbon group. The tetraalkoxysilane is tetramethoxysilane or tetraethoxysilane. The trialkoxysilane containing the hydrocarbon group is trimethoxysilane or triethoxysilane whose Si atom is bonded with an alkyl or phenyl group having 1-6 carbon atoms.
